This is unlikely to be the cause of the problem. It looks like
pulseaudio attempts all possible configurations for devices when loading
them to find out which ones work.
I've noticed that I get the same floating point exception when
attempting to use the a52 plugin without pulseaudio
Here's what gdb has to say about that core dump:
Core was generated by `speaker-test -Da52:CARD=PCH -c6'.
Program terminated with signal 8, Arithmetic exception.

Title:
ac-53 (a52 plugin) core dumps
I think it might be an Alsa bug, not a pulseaudio bug.
My setup is: computer - TV - receiver, all connected through HDMI. Due to
hardware limitations, the TV is only capable of passing through 2 channel AC3.
So I was using a similar .asoundrc to reencode any multichannel audio to AC3.
a52 hardcoded iec958:
if (! pcm_string) {
snprintf(devstr, sizeof(devstr),
iec958:{AES0 0x%x AES1 0x%x AES2 0x%x AES3 0x%x
%s%s},
IEC958_AES0_CON_EMPHASIS_NONE | IEC958_AES0_NONAUDIO |
Status changed to 'Confirmed' because the bug affects multiple users.

default channel of a52 is 6 , so your config fail when pulseaudio use
iec958-ac3-surround-40

Which is fine, but why has it suddenly decided to ask for 4 channels?
The config file specifies 6. All this worked perfectly until the
upgrade.
